Enhance zERT discovery to be more accurate in recognizing and recording TLS sessions with very large handshake messages and unusual timing

zERT discovery is currently unable to recognize TLS sessions when handshake messages exceed the maximum TLS record length. It also relies on timers in specific situations that can sometimes generate misleading information regarding TLS sessions that slightly exceed the bounds of those timers. Please enhance the zERT discovery logic to:

  • handle TLS handshake messages that span TLS records as well as

  • TLS sessions that exceed timer boundaries in cases where watching for specific handshake data or connection behavior can be used to generate more accurate results.
